Abstract
A new type of optical solitary wave is shown to exist in W-type single-mode fibers. These solitary waves consist of localized structures separating two uniform fields of different frequencies. Their application to optical communications is considered. We show that their topology is adapted to the nonreturn-to-zero modulation format and that their fundamental features offer important advantages with respect to the usual soliton transmission scheme.
